Right now the law says "you can't brath test me" WITHOUT A REASON.
Not really. The law says that the evidence obtained as a result of the breath test won't be admitted in court if the officer didn't have reasonable grounds for the demand. But there is no-one at the roadside making sure the officer has reasonable grounds (or a reasonable suspicion) - he says blow, you blow. Or he arrests you for a refusal. Either way, the existence of a reasonable suspicion is something that only gets litigated later in court.
And guess what - that only happens if you FAIL the screening device test.
Under the new system, as under the current system, if you pass - you go on your way - and the existence (or absence) of reasonable grounds simply never sees the light of day.
Under the new system, as under the current system, the "innocent" are minimally inconvenienced (and yes, their rights are violated - minimally) for the greater good of getting drunks off the road. Stamp your feet and shake your curls all you want - that's the reality. And it won't result in the Gestapo kicking in your door in the middle of the night to haul you to a concentration camp, so why don't you just give that noise a rest.
